ALVIN DAVIS FUFFER, OF MEDFOILD, MASSACHUSETTS.

FITTING FOR SODA-WATER APPARATUS.

SPECIFICATION forming part of Letters Patent No. 323,383, dated July 28,1885.

Application filed February 9, 1835.

To all whom it may concern,.-

Be it known thatl l, ALvIN vDevis Pnrrnn, a citizen ofthe United States,residing at Medford, in the county of Middlesex and State ofMassachusetts, have invented certain new and useful Improvements inFittings for Soda- TVater Apparatus; and I do hereby declare thefollowing to be a full, clear, and exact description of the intention,such as will enable others skilled in the art to which it appertains tomake and use the saine, reference being had to the accompanyingdrawings, and to letters or ligures of reference marked thereon, whichform a part ot this specication.

This invention relates to draft-cocks for soda-water apparatus and meansfor attaching the same thereto 5 and it consists in the construction andarrangement ot parts hereinafter set forth and claimed.

In Figurel, Ihave shown, at A, a vertical central section of a portionof the shell ot' a sodawater fountain to which a discharge-cock, B. isattached, and in the general combination of parts as an entirety isembodied the subjectof my invention. The outside or steel shell of saidfountain, as shown at a, is provided with the usual lining, l), of tin,to maintain the purity ci' the contents. To obtain a medium by which tosecure the discharge-cock B to the fountain A, I have constructed atubular bung, C, both interiorly and exteriorly screwthreaded, at c andd, respectively. Upon the outside one, d, is litted the clamp-nut I), bymeans ot' which said bung is tlrmly attached to the fountain and formsan integral part thereof, while the interior one, c, receives andcontains the shank E, exteriorly screw-threaded, of the cock B.

Upon the lower extremity or portion of the bung C, which lies within thefountain, I have cast or formed an external shonlderd, which rests underthe shell et ot' the fountain, while asimilar oppositely-disposed butcorresponding shoulder or annular lip, g, is shown as projecting withinthe bore ot' the bung C. This annular lip g forms a seat, upon which Idis ose the )ackinfr F, while from the dis )o- P l s l sition of theparts it is evident that the lower extremity of the shank E of the cockB,when the latter is in proper position, will compress said packing, andthus secure a tight joint to prevent access of the huid contents of the(No model.)

fountain from entering the screw-threads, as usually occurs initier thepresent system of securing the cock to the bung of the fountain 5 5 orother vessel.

The discharge-pipe leading from the fountain is shown at G, secured tothe cock B by solder, (shown in blacln) and unites with the maindischarge-outlet II, which is formed in 6o tin or other suitable metal.

From the above descriptionit will be readily understood that the actionof securing the discharge-faucet B when in place compresses the packingF and the screw-threaded surfaces 65 upon the cock, and itsretaining-bung (l cannot be reached by the fluid contents-such as sodaor mineral water-contained within the vessel. Thus, incase the tin ersilver coating wears from oli the screw-threads and exposes 7o the brasscomposing them, this metal cannot produce any deleterious eti'ect uponthe beverage, and the purity of the latter is effectually preserved.Furthermore, the destruction of the metal forming the fittings isobviated, 7 5

and the several parts may be taken apart more readily, will last.longer, and at the saule time a tight nt can always be secured withoutsubstituting new parts.

In Fig. 1 I have shown the parts as adapted 8o and arranged inconnection with a steel sodawaterfountain orother analogous vessel,while in Fig. 2is a slightly-modified form, as adapted to be employedwith copper fountains; butin both cases the result and object of myinven- 8 5 tion is accomplished in substantially the same manner, andconsists in preventing any access whatsoever of the contents of afountain or vessel under pressure te the peripheral screwthreadedsurface which exists between the 9o bung and the dischargecock.

It is very evident that various modifications may be introduced bypersons skilled in the art in the method of constructing and forming theinterior annular lip or packing-seat, g. 95

Thus by means of one ot' these, which is shown in Fig. 3, I am enabledto adapt the old form of bung C', so that it will accomplish the objectand purpose of my invention. In said Fig. 3 the ordinary bung` isinteriorly screwroo threaded its entire distance, and I have thereforeformed the interior lip separate and distinct from the bung, casting anannular piece, g', exteriorly screw-threaded, and of a dian1eter adaptedto be screwed in the bung and secured permanently in place by solder orothercock B with retaining-bung C, having` lip g, the draft-pipe Gr, andthe paekingF, said cock compressing said packing to form a tight joint,substantially as set forth.

In testimony whereof I affix my signature in presence of two Witnesses.
